FAQs
Question: What is a binary tree? Answer: A binary tree is a data structure where each node has at most two children, referred to as the left and right child.
Question: Why is traversal important in binary trees? Answer: Traversal is essential for accessing and processing each node in a binary tree systematically.

Q. How do you determine the height of a binary tree?
A.
Count the number of nodes
B.
Count the number of edges
C.
Maximum depth of any node
D.
Minimum depth of any node
Solution
The height of a binary tree is defined as the maximum depth of any node, which is the longest path from the root to a leaf.
Q. What is the space complexity of recursive tree traversals?
A.
O(n)
B.
O(log n)
C.
O(1)
D.
O(n log n)
Solution
The space complexity of recursive tree traversals is O(h), where h is the height of the tree. In the worst case of a skewed tree, this can be O(n), but for balanced trees, it is O(log n).
Q. Which traversal method is not suitable for binary search trees when you want to delete nodes?
A.
Inorder
B.
Preorder
C.
Postorder
D.
Level order
Solution
Preorder traversal is not suitable for deleting nodes in a binary search tree because it visits the root before its children, which can lead to incorrect deletions.
